. "Be :it known that I, DUNGATN A. L. Mo-

DONALD, a subject of the King of Great Britain,.and a resident of Montreal, Province of -Quebec, Dominion of Canada, andwhose post-office address is care ofMontreal Street Railway Company, Montreal, Canada, have invented a new and useful Improvementm Turnstile Mechanism, of; which thefo1low-' ing'isa specification. i

The object of my invention is to provide a car of this class'which will permit one passenger to be on a given portion of the platform at a time, so that fares can be collected without confusion, and from each passenger as he passes 'thispart ofthe platform.

1 This object isaccomplished by my invention,

one embodiment of which is hereinafter set forth. I

L Foramore particular description of invention, reference is to be had to the accompanying drawings, forming a part here-L of, in which Figure 1 1s a perspectiveiview of a portion. of the car provided with my improvement Figg'2'is a planview ofaportion of the mechanism. Fig. Bis a similar viewexcept that the parts are show'nin a. different posi- 6 being taken'on thelines 5+5 and .6-6, respectively, of Fig. 4, looking in the direction of the arrows, with parts omitted. Fig? 7 'is a. perspective view of a pawl which is tion. Figs. 4, 5 and fiare'sectionalviews of a portion of the mechanism, Figs; 5 and a component part of the mechanism.

Throughout the various views of the drawings, similar reference characters designate similar parts.

In'the' embodiment of my invention herein 'shown, the car 1 is provided with a platform 2 which has a rail 3 which separates the outgoing from the incomin'gpassengers; The incoming passengers pass through a doorway 4; closed by a door 5, and the outgoing passengers passthrough an exit doorway 5 which may be closedby a door 7. One of the uprights 8 which supports'the rail 3 also supports, a vertically disposed shaft .9 which turns in the same and isprovided with a cam 10 that is fixed toits upper end. This cam 10 has a beveled surface which ri'des over a trigger or lever'12 that extends from the register 13 so that, a movement of the team 10 through an angle of about degrees will shift the lever 12 once and cause W QC AN A It m nth; r N R AL, Q IEB Q AN D Q;a i on .21 0. TTnEQPAY-a oonronn'r'ron, onlvnw Yonx, 1v. 'Y., noonrormrron oninnwf f atahttauahfv; 1 91 1 the register 13 to register a fare. "Immedi-i' ately" above the railing 3 the shaft 9*car'ries a bar 14: which is fixed thereon and opposite the doorway 1, so that/a passenger must shift this bar 14 substantially 90'degreesto matically'registers a fare. u

It is. obvious that if the mechanism that 7 confinedl'towhat has'been described indetail i V above, "that when the bar '14 is once thrown,

as shown in dotted lines inFig. 1, any hum ber of passengers could enter"without further reglstering their fares. "To prevent,

thisadditional mechanism is requiredn The rail '3 is enlarged to form a casing 15 in which is placed this mechanism The shaft 9 carr'iesa crank 16 on which is a'crank pin 17 fixed inthe conventional manner, and this f crank pin'17 is'connected to two links 18",

and 19, respectively. Theflink18is" at its other end,journaled on a pin 20 which is fixed in a short link. 21thatis loosely mounted on a vertical shaft 22. This vertical shaft 22 hasfa ratchet wheel 23 fixed thereonfso that'it'isadapted to beengaged by the pawl 24Lmounted on the short link 21 and pressed; aga nst the ratchet 23,.by means {of aleaf spring 125 whichis also secured upon the link 21, in the conventional manner; The shaft 22- also carries a link 26 which hasa pawl, 27 and a leaf spring 28 all mounted and connected the same as the link 21 and its' pawl 2 1'and spring 25, except that the link 26 is pivotally connected to thelink 19 by'means I of a pin 29. The link 19 isalso provided with an eyelet 80 to which is connected a coil spring 81 that runs to a second eyelet .32 .PZ, fixed on theinteriorof the casing 15. The

links 18 and19, -are,-for the sake of clear- .1

ness, removed from Fig. 6 but indicated in:

another relativeposition by dotted lines.

The links 18and 19 togetherwith the con: if I 'neoting parts are'so arranged and disposed that when the bar lt is thrown throug'h'an angle, the link 18 throws the ratchet 23=and ioo the shaft 22 through a corresponding angle j and when thebar 14 is restored to its former position through the action 'of the spring 31, the link 19 through the small link 26 and ratchet 23 throws the shaft 22* through a second angle'equal to the first.

The shaft 22 has fixed thereon a bevel gear 33 immediately below the ratchet 23 or some other convenient. location, and: this bevel gear 33 engages a second aughty-11o. I i

34 on a short stud shaft 35 at the end of which is mounted an arm 36 in any desired manner. This arm 36 is mounted so as to be symmetrical of the shaft 35with which it revolves.

The shafts 22 and 35 are stud shafts with their axes at right angles to each other and both are journaled in the railing 3, the stud shaft 22 being j ournaled in the casing 15 as well. The bars 14 and 36 are so placed with regard to each other that when the bar 14 is across the doorway 1, the bar 36 is vertically disposed as shownin Fig. 1. When the bar 1 1 is thrown through the doorway 4 so as to permit the entrance of a passenger, the bar 36 is thrown into a horizontal position, as indicated by dotted lines in Fig. 1. The length of the casing is such that there is only room for one passenger between the 1 bars 36 and 14, so that it is easy for the conductor of the car to prevent more than one passenger being opposite the casing 15 at one time. The passengers leaving the car do so through the doorway 6 and are prevented from mixing with the entering passengers by means of the rail 3.

From the foregoing it is obvious that my invention providesa simple mechanism for admitting oneperson at a time into the interior of a car and simultaneously registering the number of persons so admitted.

While I have shown and described one embodiment of my invention, it is obvious that it should not be restricted thereto but that it is broad enough to cover all structures that come within the scope of the annexed claims.

In my Patent No. 1,016,948 issued to me February 13, 1912, application for which was filed of even date herewith, I have shown and claimed the broad features herein ClISClO'SGd but to which no claim is made in this my pending application.

What I claim is:

1. In a device of the class described, combination of a railing, a doorway, two bars, one adapted to normally rest across said doorway and the other in a vertical position, and link mechanism connecting said bars so that when one is shifted in said doorway, the other is moved to a horizontal posltion.

2. In a deviceof the class described, a

railing carrying two bars, one mounted on a vertical and the other on a horizontal shaft, and link mechanism connecting said shafts so that when the one mounted on a vertical shaft is shifted through an angle and back, the one mounted on a horizontal shaft is shifted twice the angular distance in one direction. 3. In a device of the class described, a car with entrance and exit doors, a platform, a railing separating the said doorways, a horizontally disposed bar carried by said railing, a bar with a horizontal aXis carried by said railing and link mechanism connecting said bars, so that when the horizontally disposed bar is thrown through an angle and back, the bar with a horizontal axis is thrown through twice the angle in one direction.

Signed at the city of Montreal, this 22nd day of August, 1910.
